Nissan has engineered a diverse range of diesel engines to power its vehicles, each designed to meet specific performance and efficiency needs. Below is an overview of some notable Nissan diesel engines:
1. The mighty patrol with the TD42 Engine
Introduced in 1987, the TD42 is a 4.2-liter inline-six diesel engine renowned for its durability and reliability. Featuring a cast-iron block and cylinder head, this naturally aspirated engine delivers between 115 to 125 horsepower and 265 to 275 Nm of torque. Its robust construction has made it a favorite among off-road enthusiasts and in commercial applications. Notably, the TD42 is celebrated for its longevity, often exceeding 500,000 kilometers with proper maintenance.
2. The ‘Hand Grenade’ ZD30 Engine
The ZD30 is a 3.0-liter inline-four diesel engine that replaced Nissan's earlier QD, BD, and TD series engines. It features a cast-iron crankcase and an aluminum-alloy crossflow cylinder head with dual overhead camshafts operating 16 valves. The engine has been utilized in various models, including the Nissan Patrol and Navara, and has undergone several iterations to improve performance and meet stricter emission standards.
3. ZD30 CRD (Common Rail Diesel) Engine
In 2007, Nissan introduced a major revision of the ZD30 engine, incorporating common rail direct injection technology. This update aimed to enhance fuel efficiency and meet updated emission standards. The common rail system operates at a pressure of 1,600 bar, managed by an improved ECU. This version also features a hot EGR system with a heat exchanger to reduce NOx emissions.
4. YD25 Engine
The YD25 is a 2.5-liter inline-four diesel engine equipped with common rail direct injection and a variable geometry turbocharger. Initially producing 128 kW and 403 Nm of torque, the engine was updated in 2010 to deliver 140 kW and 450 Nm. It has been widely used in models such as the Nissan Navara (D40) and Pathfinder (R51).
5. V9X Engine
Developed by the Renault-Nissan Alliance, the V9X is a 3.0-liter V6 turbo-diesel engine. It produces 170 kW of power and 550 Nm of torque, with peak torque available from as low as 1,750 rpm. The engine features a single turbocharger located within the engine's V configuration and utilizes a Bosch common rail fuel injection system operating at 1,800 bar. This engine has been fitted in various models, including the Nissan Navara (D40), Pathfinder (R51), and several Infiniti vehicles.
6. YS23 Engine
The YS23 is a 2.3-liter inline-four turbo-diesel engine introduced in the Nissan Navara (D23) series. It features a twin-turbocharger setup, delivering a balance of performance and efficiency. The engine produces approximately 140 kW of power and 450 Nm of torque, offering improved fuel economy and reduced emissions compared to its predecessors.
